x402-gated HR document endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com serves an HR document resource (document ID 32) behind an x402 paywall. It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.
The specific endpoint `/api/v1/hr/documents/32` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (asset 0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no description of what the HR document endpoint actually returns. The endpoint is live (returns a valid x402 402 challenge), but without documentation it is unclear what input the POST body should contain or what shape the response takes.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no indication of what the HR document endpoint actually returns. The listing is effectively a stub.
